Four specialized laboratories at the University of Oslo (UiO) are equipped to pursue a wide set of state-of-the-art techniques to study the dynamics and structure of flow in two- and three-dimensional porous media.
We have a full range of high-resolution and high-speed imaging techniques, including two ultrafast Photron Ultima (SA5 and APX) cameras with 7000 fps at a spatial resolution FLIR SC300 infrared camera used for real-time measurements of heat dissipation in fractures, hydro-fractures and porous media flows and a wide variety of DSLR camera and accompanying optics. Microscale experiments can be imaged via far field microscopy using a Zeiss Stemi 2000-C distorsion-free stereo microscope which couples to our high-speed and high-resolution cameras.
Flicker-free illumination sources tailored for the different applications (including high-speed microscopy) are also available.
We have also recently bought a Krüss DSA25 drop shape analyzer to perform direct measurements of surface tension, wetting properties and surface free energy.
Additionally, our laboratories include a large set of different optical equipment, such as lasers with different intensities and wavelengths, lenses and other optical components, cameras and microscopes for Particle Image Velocimetry.
We are also well-equipped to perform homodyne correlation spectroscopy for the measurement of particle velocity fluctuations in fluids, diffusion constants and viscosities.
In addition to this wide variety of state-of-art techniques, our laboratories are also fully equipped with standard fluid mechanics labware, such as capillary viscometers, high-precision scales, pressure and temperature sensors, surface treatment chemicals for the control of wetting properties and general laboratories glassware.
